The present protocol combines ex vivo stimulation and flow cytometry to analyze polyfunctional T cell (TPF) profiles in peripheral blood mononuclear cells (PBMCs) within Japanese encephalitis virus (JEV)-vaccinated children. The detection method and flow cytometry color scheme of JEV-specific TPFs were tested to provide a reference for similar studies.
